REGULATING DEVICE FOR MOTORS OR ENGINES.

SPECIFICATION forming part of Letters Patent N0. 771,497, dated October4, 1904.

Application filed September 23, 1903. Serial No, 174,315. (No model.)

To all whom it may concern:

Be it known that I, FRITZ REICHENBAOH, civil engineer, a subject of theKing of 'Prussia, German Emperor, residing at N o. 14 Bismarckstrasse,()harlottenburg, in the Kingdom of Prussia, German Empire, have inventeda new and Improved Regulating I)evice for Motors or Engines, of whichthe following is a specification.

This invention relates to a regulating device for motors and engines ofall kinds in which the movement of a governor is transmitted to theregulating parts of the power-motor by means of a liquid.

The governor to be used with this device is preferably constituted by apump of some suitable kind which produces directly the pressure of thetransmitting fluid.

The new regulating device is completely free from friction and can beeasily applied even when the motor is very compact and where there areseveral regulating parts and in cases where arrangement of rods wouldoffer certain difficulties.

In order to make my invention more clear, I refer to the. accompanyingdrawings, in which similar letters. denote similar parts throughout theseveral views, and in which Figure 1 is a vertical section through aregulating device constructed according to my invention. Fig. 2 is aside view of another form of construction also based on the principleembodied in my invention, and Figs. 3 and 4 illustrate furthermodifications.

Referring to Fig. l, the governor a is for the sake of simplicityarranged directly on the vertical spindle of asteam-turbine b, which inthis case represents the power-motor to be controlled. The governorconsists of a vessel (0, containing water, oil, mercury, or the like,said liquid being forced against the walls of the vessel by-centrifugalforce. In order to insure the liquid properly participating in therotation, the vessel (4 can be provided with ribs or baflies 0. Theliquid is transmitted through a fixed piped in the constructiondescribed to a cylinder with a piston f, connected with the device forregulating the admission of steam-say a throttle-valve e in thesteam-pipe. Water or oil passing into the sure of the liquid increases.transmitted to the regulating piston or cylincylinder is automaticallyreplaced in the governor. When the speed of the turbine increases, thecentrifugal force of the liquid increases as well, and consequently itspressure increases also, and liquid is forced through the pipe into thecylinder and drives the piston f outward, the piston-rod thereuponclosing the throttle-valve and compressing a spring 9, which is used toreturn the piston to its original position. IV hen it is desired toalter the speed at which the governor acts, the tension of the spring Qcan be altered as desired, preferably by means of a hand-wheel 71/. Thefluid-transmission pipe (Z is preferably bent in the direction ofrotation of the vessel a, as well as slightly inward. Thefluid-containing vessel acould alsobe fixed so that only the blades 0(which in that case would have to be secured to the spindle of theturbine) would cause the rotation of the liquid. The cylinder in whichthe piston f moves could be sccured to the vessel (4 direct either inradial or in tangential direction, as indicated in Fig. 3. The cylinderand piston could also be replaced by a pressure-gage tube, thealteration of the shape of which by the pressure of the contained liquidwould operate the regulating parts, as indicated in Fig. I, I

In amodified construction illustrated in Fig. 2 in plan a Roots pump 7:or the like is used as the governor. For the return of the liquid intothe pump there is provided a small opening k in the return or dischargepipe. hen the motor or the pump increases in speed, more liquid escapesthrough this small opening 71:, which escape is only possible when thepres- The pressure is der device and causes the engine to go slower. Byincreasing or reducing the pressure of the counteracting spring g, whichin this case may be a tension-spring, the pressure of the liquid, andtherefore the number of revolutions of the turbine, can be regulated andaltered.

Having now described my invention, what I desire to secure by a patentof the United States 1s- 1. In a regulating device for motors andengines, the combination with a rotary part or parts driven by the motoror engine, a fluid subjected to pressure and caused to move in cycle byvirtue of the rotation of said part or parts, and means for causing saidfluid under pressure to change the quantity of the driving mediumpassing to and into the motor or engine.

2. In a regulating device for motors and engines, the combination with arotary part or parts driven by the motor or engine, a liquid subjectedto pressure and caused to move in cycle by virtue of the rotation ofsaid part or parts, means for changing the quantity of the drivingmedium passing to and into the motor or engine, and means for causingsaid liquid under pressure to operate said first-n'ientioned means.

8. In a regulating device for motors and engines, the combination with arotary part or parts driven by the motor or engine, a liquid subjectedto pressure by virtue of the rotation of said part or parts, means forchanging the quantity of the drivingmedium passing to and into the motoror engine, and means for causing said liquid under pressure first tooperate said first-mentioned means and then to return to the said rotarypart or parts.

4. In a regulating device for motors and en'- gines, the combinationwith a rotary part or parts driven by the motor or engine, a liquidsubjected to pressure and caused to move in cycle by virtue of therotation of said. part or parts, means for changing the quantity of thedriving medium passing to and into the motor or engine, means forcausing said liquid under pressure to operate said first-mentionedmeans, and a pipe for leading the liquid under pressure to the meansmentioned in the second place.
